How to use PHP to implement a simple online movie on-demand and playback system

With the development of the Internet, more and more users choose to watch movies online without No more relying on traditional movie theaters or DVDs. Therefore, developing a simple online movie on-demand and playback system can meet the needs of users and has important practicality and market prospects. This article will introduce how to use PHP to implement a simple online movie on-demand and playback system, and provide corresponding code examples.

1. System Architecture Design

The online movie on-demand and playback system mainly includes three modules: user management module, movie management module and playback module.

1. User management module: used for user login, registration, movie browsing, movie collection and other functions.
2. Movie management module: used for uploading, editing, deleting and other functions of movies.
3. Playback module: used to implement the online playback function of videos.

2. System setup steps

1. Create database

First, we need to create a database to store user information and movie information . MySQL or other relational databases can be used.

Create a database named "movie_system" and create data tables named "users" and "movies" to store user information and movie information.

The user information table ("users") includes the following fields: id, username, password, email, etc.

The movie information table ("movies") includes the following fields: id, title, description, image, video, etc.

2. User Management Module

First, we need to create a user registration page (register.php) and a user login page (login.php).

register.php code example:

<?php
// 处理用户注册
if($_SERVER['REQUEST_METHOD'] == 'POST') {
    // 获取表单数据
    $username = $_POST['username'];
    $password = $_POST['password'];
    $email = $_POST['email'];

    // 将用户信息插入数据库
    // 注意：此处需要使用密码加密算法，如md5或sha1
    $hashedPassword = md5($password);
    
    // 连接数据库
    $db = new mysqli('localhost', 'root', 'password', 'movie_system');
    
    // 插入用户信息
    $sql = "INSERT INTO users (username, password, email) VALUES ('$username', '$hashedPassword', '$email')";
    $result = $db->query($sql);
    
    if($result) {
        echo '注册成功！';
    } else {
        echo '注册失败，请重试！';
    }
    $db->close();
}
?>

<!-- 用户注册表单 -->
<form method="POST">
    <label>用户名：</label>
    <input type="text" name="username" required><br>

    <label>密码：</label>
    <input type="password" name="password" required><br>

    <label>邮箱：</label>
    <input type="email" name="email" required><br>

    <input type="submit" value="注册">
</form>

login.php code example:

<?php
// 处理用户登录
if($_SERVER['REQUEST_METHOD'] == 'POST') {
    // 获取表单数据
    $username = $_POST['username'];
    $password = $_POST['password'];

    // 连接数据库
    $db = new mysqli('localhost', 'root', 'password', 'movie_system');
    
    // 查询用户信息
    $sql = "SELECT * FROM users WHERE username='$username' AND password='$password'";
    $result = $db->query($sql);
    
    if ($result->num_rows > 0) {
        echo '登录成功！';
    } else {
        echo '登录失败，请重试！';
    }
    $db->close();
}
?>

<!-- 用户登录表单 -->
<form method="POST">
    <label>用户名：</label>
    <input type="text" name="username" required><br>

    <label>密码：</label>
    <input type="password" name="password" required><br>

    <input type="submit" value="登录">
</form>

3. movie management module

First, we You need to create a movie upload page (upload.php) for uploading movie information and movie files.

upload.php code example:

<?php
// 处理电影上传
if($_SERVER['REQUEST_METHOD'] == 'POST') {
    // 获取表单数据
    $title = $_POST['title'];
    $description = $_POST['description'];
    $image = $_FILES['image']['name'];
    $video = $_FILES['video']['name'];

    // 连接数据库
    $db = new mysqli('localhost', 'root', 'password', 'movie_system');
    
    // 上传电影文件
    move_uploaded_file($_FILES['image']['tmp_name'], 'images/' . $_FILES['image']['name']);
    move_uploaded_file($_FILES['video']['tmp_name'], 'videos/' . $_FILES['video']['name']);
    
    // 将电影信息插入数据库
    $sql = "INSERT INTO movies (title, description, image, video) VALUES ('$title', '$description', '$image', '$video')";
    $result = $db->query($sql);
    
    if($result) {
        echo '上传成功！';
    } else {
        echo '上传失败，请重试！';
    }
    $db->close();
}
?>

<!-- 电影上传表单 -->
<form method="POST" enctype="multipart/form-data">
    <label>电影标题：</label>
    <input type="text" name="title" required><br>
    
    <label>电影描述：</label>
    <textarea name="description"></textarea><br>
    
    <label>电影封面：</label>
    <input type="file" name="image" required><br>
    
    <label>电影文件：</label>
    <input type="file" name="video" required><br>
    
    <input type="submit" value="上传">
</form>

4. Play module

The play module needs to create a play page (play.php) for playing users Selected Movies.

play.php code example:

<?php
// 获取电影ID
$id = $_GET['id'];

// 连接数据库
$db = new mysqli('localhost', 'root', 'password', 'movie_system');

// 查询电影信息
$sql = "SELECT * FROM movies WHERE id='$id'";
$result = $db->query($sql);
$row = $result->fetch_assoc();

// 输出电影标题
echo '<h1>' . $row['title'] . '</h1>';

// 输出电影描述
echo '<p>' . $row['description'] . '</p>';

// 输出电影封面
echo '<img  src="images/' . $row['image'] . '" alt="How to use PHP to implement a simple online movie on-demand and playback system" >';

// 输出电影视频
echo '<video src="videos/' . $row['video'] . '" controls autoplay></video>';

$db->close();
?>

3. System testing and deployment

1. Save the above code as the corresponding file and place it in a directory that supports PHP In the relevant directory of the web server (such as Apache or Nginx).
2. Run the above code and access the corresponding URL address in the browser to complete the test of the system's registration, login, movie upload and playback functions.
3. If you need to deploy to a public network server, you need to upload relevant files to the server and configure the relevant server environment and database connection parameters.

Summary:

This article details how to use PHP to implement the steps to build a simple online movie on-demand and playback system, and provides corresponding code examples. Through the implementation of user management, movie management and playback modules, the needs of users can be met and a good user experience can be provided. For developers who are new to PHP, this system has certain reference and learning value, and can be used as a practical development practice project. Of course, the functions and performance of the actual online movie on-demand and playback system are more complex and complete than those introduced in this article, and require further development and optimization.
